TYPEWRITING MACHINE Filed Dec. 19, 1927 Patented Oct. 13, 1931 UNITED[STATES PATENT OFFICE HENRY RESGH, OF BAYONNE, NEW ERSEY, ASSIGNOR TOUNTDERWOOD ELLIOTT FISHER COMPANY, OF NEW YORK, N. Y., A CORPORATION OFDELAWARE TYPEWRITI NG MACHINE I Application filed December 19, 1927.Serial No. 240,991.

This invention relates to typewriting m'achines wherein an auxiliaryinking ribbon is interposed. between superposed work-sheets formanifolding, especially of bills or statement-sheets and a record-sheet.The invention is shown in connection with an auxiliary ribbon-device,such as disclosed in co-pending application of Jesse A. B. Smith, SerialNo.

17 7 ,884, filed March 24, 1927, (now Patent No.

1,764,900, dated June 17, 1930), and deals largely with means forguiding the leading end of work-sheets up past the printing line, theobject being to minimize time and labor during their insertion aroundthe platen from the rear thereof.

The auxiliary ribbon is fed from aspoolat one side of theplaten-carriage down to the printing line, then in a horizontal stretchalong the printing line to be led up again and wound upon acorresponding spool opposite the first one. The horizontal or active.stretch of the ribbon is held upon the printing line close to the platenby a displaceable ribboncarrier, which allows said active stretch to beswung upwardly and forwardly clear of the platen when the record-sheetis to be inserted from the rear. Difficulties have been experienced wheninserting a' record-sheet with the auxiliary ribbon in raisedinoperative position, in that the leading edge of the paper, normallyflaring away from the platen-surface at the front thereof, would clashwith the auxiliary ribbon or parts of the ribbon-holder, causing theoperator to use her fingers in guidingthe leading paper-edge rearwardlyto prevent its getting wrinkled or injured.

. According to this invention a displaceable paper-guide is provided,which, normally out of function, may be rendered active to guide ordeflect the paper across the typing line closely to the platen-surfaceand clear of the obstructing parts, when the auxiliary ribbon is swungto inoperative position.

. Preferably the displaceable ribbon-holder and the displaceable.paper-guide are cooperative and timed to each other in such a 'waythatthe movement which displaces the active partofthe auxiliary ribbonautomatically causes the paper-guide to deflect the being displaced toinoperative position, said pam-member will bring the blade-likeaperdeflecting part of the leveragainst suitable spring-pressure into.proximity with the platen-surface.

After the record-sheet is positioned, the inking ribbon is restored fortyping while the paper-guide recedes, and a small bill or statementsheet is usually front-inserted over the ribbon and record-sheet. a

It is understood that a movable front paper-guide substantially asherein proposed may also be used'with advantage as a mechanism in itselfor in connection with other attachmentsor devices and wherever a certainguidance of the leading paper edge over and beyond the typing line isdesired for convenienceduring insertion.

Other features and advantages inafter appear.

guide or deflector 14 as hereinafter described.

Figure 1 of the drawings shows an auxiliary inking ribbon 15 forduplicating purposes, operative upon-the platen between a recordsheet 16and a statement-sheet 17, the latter being written upon by means of ausual typebar 18 and the usual oscillating ribbon 19 (fractionallyindicated in dot and dash).

The mechanism which handles the auxiliary ribbon is in the form of anattachment mounted upon the ordinary Underwood platen-frame and hereinshown to include brackets 19* mounted upon the flanges 20 which form thetop of the sides 11. Said brackets 19, in effect forming continuationsof the sides of the platen-frame, may be rigidly interconnected by anintegral cross-bar 21. Said bar carries, at either end, and mounted uponthe back face thereof, a rising bracket 22, upon which is mounted aspool 23 by means of a stud or axle 23 to handle the auxiliary ribbon15, which is carried from one spool downwardly to the typing line, thenalong the typing line to present a horizontal or typing stretch to thetype-bar, to be led upwardly again for delivery upon the other spool. Amechanism to feed the ribbon is not shown on the drawing althoughindicated by a 1ratchet-wheel 24 shown on the left-hand s 00 Aribbon-deflector or angle guide 25, over which the ribbon folds,adjacent either end of the platen, determines the horizontal stretch ofthe auxiliary ribon, said deflectors forming part of a swingableribbon-carrier, which serves to displace the horizontal part of theribbon to allow the advancing front edge of the record-sheet to crossthe typing line when being inserted from the rear. To constitute theswingable ribbon-carrier, the deflectors 25 form the terminals of a flatbar 26, which, in addition, has forward angular extensions 27 whichconfine the ribbon-carrier between brackets 28 mounted upon the frontface of the above-mentioned connecting cross-bar 21. These extensionsare formed at the ends with vertical arms 29 (see Figure 1), both ofwhich have double pin-and-slot connection with their adjacent brackets28,

the slots being shaped in such manner as to guide the ribbon-carrier ina suitable shift- To shift the ribbon-carrier in its slots, :1rock-shaft 29 is journaled in the brackets 19 and operable by a lever 30formed with a finger-piece 31. Forwardly-extending crank-arms 32 are.secured to the rock-shaft 29 to align with the outer side face of eachbracket 28, with the free ends provided with studs 33 that pass throughslots 34 provided in said brackets 28 concentrically to the rock-she. ft29, said studs 33 to pivotally support the upper ends of the pair ofvertically-disposed arms 29. The lower parts of the arms 29 carry studs34 that pass through slots 35 and are slidably held against the faces ofthe brackets 28 by the heads of the studs bearing against the oppositefaces of the brackets 28. Slot 35 is a compound slot and formed by themerging of two arcuate slots 36, providing for an intermediate positionof the ribbon-carrier (not shown on the drawing). Raising of thefinger-piece 31 results in rocking the shaft .29 to raise the arms 32 toadvance the studs 33 and 34 along their respective slots from the normalposition of Figures 1 and 2 to the position shown at Figure 3. At 37 inF igures 3 and 4 are indicated paper-guiding members in the nature ofthe usual wingscales disposed at either side of a usual typeguide 37*and stationarily mounted upon the machine-frame. These members 37 are toguide the worksheet from the deflector 13, until close to the typingline, and, in the present case, are provided with horizontal flanges 38at the top for the further purpose of facilitating the front insertionof small worksheets. A cam-pin 38 is rigidlv provided upon the innerface of each bracket 28 and co-operates with a cam-face 39 formed uponthe vertical arms 29, so as to assist in guiding the movableribbon-carrier when the studs 34 thereon are sliding from intermediateto upper extreme position within the compound slots 35. A detent-sector40 is secured upon the left-hand end of the rock-shaft 29 and has threenotches 41 to co-operate with a pawl 42 held under spring-tension 43,said notches corresponding to extreme and intermediate 119 positions ofthe rock-shaft- 29 When a record-sheet is to be inserted at the rear ofthe platen, to be positioned under the auxiliary inking ribbon, thelatter will be displaced, as described above, from its posi- 115 tion inFigures 1 and 2 to the Figure 3 position. A glance at Figure 3 showsthat the leading edge of the paper, if not otherwise directed, is liableto flare away from the plat-- en-surface in leaving the scales37 andcatch 12 on the auxiliary ribbon 15 or parts of the ribbon-carrier, ason the flat bar 26 or the rock-shaft 29 requiring the operatorsattention to manually deflect the paper to the rear, clear of theobstructing parts.

,The novel deflector 14*, designed toimprove this manual paper-guidingoperation, includes a. lever 44 of flat material, which, intermediateits ends, has integral bent-over cars 45' to receive a fulcrum pin orscrew 46, 130

supported upon a U-shaped bearing member 47 (see Figure 3), which isscrewed at 48 to the front rail 49, which is of angular crosssection andis part of the platen-frame men- 5 tioned above. The lever 44, at itsright-hand end, is formed withan upward angular extension 50, to presenta cam-face for a cam-member 51, the latter forming a lower extensionupon the right-hand vertical arm 29 of the ribbon-carrier. As theribbon-carrier is raised, a bent-over end 52 of said extension 51 willurge said angular extension 50 of lever 44 against the pressure of aleaf-spring 5 3 to cause the opposite end of the lever 44, which isenlarged to form a paper guiding or deflecting blade 54, to swingtowards the platen substantially to take the place of the nowineflective ribbon- (see Figure 3). The paper-guiding blade 54 is shapedto conform Ito the platen-surface, and, while having proper clearancetherewith, is effective to deflect the record sheet, to clear theobstructing ribbon-mechanism, said record-sheet being inserted and fedaround the platen with the aid of usual feed-rolls 55.

After the record sheet is positioned, for type manifolding, thefinger-piece 31 may-be depressed to lower the auxiliary ribbon toworking position (see Figure 2), simultaneously causing thepaper-guiding blade 54 to recede to ineflective position, as clearlyseen from Figures 1 and 4. The bill or statement sheet 17 then may befront-inserted over the auxiliary ribbon 15, and collated over the 35record sheet upon the usual collating table and between the collatingmembers 56, which are fast to the connecting cross-bar 21.

It will be understood that by a single operation of lifting thefinger-piece 31, the ribbon is displaced from the typing line and thedeflector 54 displaced to apaper-deflecting position at the platen andboth deflected members locked by the detent 42 in their key-displacedpositions, leaving the operators hands 4 free to insert a record-sheetto the feed-rollers 55, and, by a forward spinning movement of theplaten, the record-sheet is quickly advanced over the typing line andunder the ribbon to the first typing line thereon,the

displacements being automatic to the manual operation of thefinger-piece. It will be noted at Figure 2 that the spring 53 normallyholds the deflector 54 against the carriage rail and that the detent 42holds the ribbon- 55 carrier away fromactual contact with the platen andprevents actual contact between I the arm 50 and the cam '51, so thatthe ribbon-carrier can adjust itself to various thicknessesof'supe'rposed manifold sheets; and

that the working space shown between the cam and arm provides clearancefor initially liftng the ribbon vertically over the typingline beforemotion is conveyed to the deflector to avoid possible interferencebetween the i disp'laceable. deflector and ribbon.
